DETONATING DEVICE.

SPECIFICATION forming part of Letters PatentNo. 715,130, dated December 2, 1902. Application filed Ncvember 3,1902. Serial No. 129,990. (No model.)

.To @ZZ whom. it may concern:

Be it known that I, ROUSSEAU H. OPES, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Detonating Devices, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to detonating devices having a detonating-chamber and a movable plunger operating therein to explode a torpedo placed in the chamber intermediately of the plunger and chamber-walls.

The object of such invention is to provide a structure which may be economically constructed and embody the requirements necessary for safety and facility of operation, and particularly to avoid the sticking of the bolt to the detonating-head during the construction or operation of the device.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various forms in which the principle of the invention may be used.

In the annexed drawings, Figure 1 is a front elevation of the preferred form of the detonating device embodying the principles of my invention. Fig. 2 is a longitudinal sectional view, on an enlarged scale, taken through the center of Fig. 1 and showing the parts in p0- sition before exploding a torpedo. Fig. 3 is the same as Fig. 2, but showing the parts in position during the explosion; and Fig. tisa modified form of my improved device, showing a downwardly-tapering bolt.

A, Fig. l, is the head of my improved device, provided with a bore a at its upper end, into which may be inserted a cane or staff b, by which the device is operated. Cast integral with the sides of the bore ctandimmediately below the bore is a conical detonatingbolt c of increasing diameter from top to bottom. The bottom of the bolt is cast within an explosion-chamber B, the sides of which are slanting and form a conical opening d out of the chamber, which increases in diameter as it approaches theinterior. The outer end of the opening d is somewhat less in diameter than is the diameter of the bottom of the bolt c, so that while the base ofthe device cannot be shaken loose from the head when the de- Vice is being carried, as illustrated in Fig. 2, neither is any part of the head, with the eX- ception of the bottom of the detonating-bolt, in contact with the explosion-chamberduring the explosion, as illustrated in Fig. 3. The diameters and lengths ofthe opening d and the bolt c are such that a substantial opening between the bolt and the sides of the chamber is left for the escape of gases of explosion when the bolt is pushed into the chamber and occupies its innermost position just prior to explosion. This feature greatly reduces the danger of breaking of the bolt-head by offering a very free avenue of escape to said gases. Through a small opening ein the side of the explosion-chamber B a torpedo j', Fig. 3, may be placed upon the bottom of the same. The detonating-bolt c and the explosion-chamber B are cast in one operation in the manner well known to those skilled in the art, the bolt being at the time of casting midway within the chamber, so that it is not only not in contact with the latter at any point, but is everywhere separated from it by a considerable distance, and thus there is no danger of sticking during the casting.

Making the sides of the explosion-chamber parabolic and the detonating-bolt so that it may be driven upward are modified forms of my device, the latter of which is illustrated in Fig. 4; but in all forms the essential feature of the tapering bolt procures the advantages and obviates the difficulties hereinbefore described.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by the following claim or the equivalent of such stated means be employed.

I therefore particularly point outand distinctly claim as my invention- In a detonating device, the combination with an integral detonating-head formed with an explosion chamber, an opening leading ing for gases of explosion will be formed when thereto for the introduction of torpedoes, and the bolt is moved into the chamber. lo a second aperture of conical form leading out Signed by me this 1st day of November,
